The endless search for the best and most effective workout is an exhausting pursuit. From bungee dancing to skateboarding Pilates, the never-ending wave of obscure fitness fads can leave you feeling utterly defeated and embarrassingly uncoordinated.

So when one accidentally stumbles upon the secrets of the world's fittest supermodels, one feels it is their duty to share it with the weary women of Australia.

Lizzie Bland has been counting me through my burpees and side straddles at the Lean Bean pilates studio in Bondi for a little over a year. But, just last week, somewhere between my hip thrusts and downward dogs, she casually mentioned that Victoria's Secret angel Victoria Lee has been a long-time client and drops by for a circuit session whenever she's in town.

The Lean Bean classes move quickly through each movement with very little rest in between, which means there's very little time to consider just how buggered you might actually be. Before you can say "no more jump squats!", you've smashed out a full-body session and worked up more than a small sweat.

The classes are fast, furious and, most importantly, fun! I genuinely look forward to every session and feel mentally and physically strong by the end. All of Lizzie’s workouts move to the beat of her favourite remixes and there’s moral support to be found in her cute sidekick, Artie the toy poodle.

Of course, Victoria's Secret models also attribute their impossibly lean limbs to diet and freakish genetics. But if this workout is good enough for an angel, it's got to be worth a try for us mere mortals.

A warning though: Don't be fooled by Lizzie’s tiny stature and sweet smile. She is mean. Like, really mean!
